T0 ALL WHOM IT MAY-CONOERN:

Be it known that I, GEORGE R. BRAMHALL, of Chicago, inthe county of Cook, and State ot Illinois,'have i invented a new and useful Improved Apparatus for Lowering or Sinking Cylinders and other heavy weights and I do hereby declare and make Aknown that the following is a full, clear, and exact description ot' the same, reference being had to the accompanying drawings, andthe letters and figures marked thereon, which form part of` this` specification. i

My said invention has particular reference to a machine for lowering and sinking beneath the water sections of a tube or cylinder, where said sections are to be secured and bolted together, so as to form a cylinder or Well, it being necessary toiseeure the heavy sections together above the water, and gradually lower the lower portion of the cylinder into the water as the successive sections thereof are attached to the top, as hereinafter more fully described. i

To enable those Vskilled in the art to make and use my said invention, I will proceed to describe the same with particularity, making reference in so doing'to the aforesaidI drawings, in which- Figure l represents a plan or top view of my invention.

Figure 2 is a vertical central section of the saine, and

Figure 3 is a side-view of' a device to be pla-ced over the cylinder, to enable the same to be raised up or pressed down into the soil, as desired. i

Similar letters of reference in the several iigures denote the same parts oi" my said invention.

A represents a crib, constructed in the manner of a coder-dam, enclosing a well-hole, B, which is filled withl water.

C represents a cylinder in theprocess of being lowered, C being a section thereof, which is to be placed upon the upperend of the cylinder C, and secured t'lrereto, as hereinafter specified.

D represents an inclined way or slide, upon which the cylinder moves and rests during the operation, to the upper end of which way D 'is hinged a prolongation thereof, marked D', which may be lowered parallel with the surface of the crib, or may be raised up, so as to lie in the same-inclination with D, forming a continuation thereof in a right line, said movement being eifected by means of ropes and tackling, as indicated, as by loosening the cord a and drawing upon the cord b the platform D is lowered, and by loosening Z1 and drawing upon a it is raised, the tackling ot' the rope a being attached to a cross-bar upon the uprights 'H I-I, as shown in the drawings. y

In operating my invention, the platform Dl is lowered parallel to the crib-licor or top, and one of the sec` tions of the cylinder is placed thereon, and a clamp, F and f, is arranged, securely binding said section tothe platform, which is then raised up, to allow said section to slide down, -liooks and links L being attached to -its upper (3nd and passing through a head-block upon the end of the platform, where it is secured by a nut, n, asA

seen in iig. 2.

A cord or chain or chains, d, are secured tothe lower end of the section, and to the tackling of the cords or chains e, which pass back to a cupstan, as seen in fig. 2. 4

When the platformis raised up in a line with the ways D, the weight of the cylinder or section is allowed to come upon the chains and the hooked rod h, when the clamp F is loosened slightly, and the section is permitted to slide down upon the ways D until the upper end of the section lies about two or three feet below the.

joint connectingithe way D and the platform D, for the purposes hereinafter set forth and described, in which position said section is clamped to thev ways D by a similar clamp to thatused in securing it to the platform.

The platform is 'again lowered, and another section of the tube or cylinder is placed and secured thereon,

when the platform israised partly up, and the upper section is allowed to slide down as before, balancing overl tile-hinged point nntii its lower end should have reached that position, so-tll'at the raising of the platform in a line with the ways will -cause the lowerend of the upper section tp rest squarely upon the lowerL section, which Ylies above the surface of the Water, where thetn'o sections are tirmlybolted together, when the Whole are low;

v the lower end rests upon a hoek or support, Z, represented in lig.

ered as before, by the means aforesaid, until the upper end of the top sections passes the proper distance below the joint g, before mentioned, when the clamp is tightened, and the chains c held firmly u-pon theeapstan.

The nut n upon Athe rods 7i is turned, to permit the section to descend until the end thereof rests upon the top ofA the lower section, forming a support at the same time.

The above-described operation is continued until all the sections areV lowered and secured together, -when After the lowering of th e cylinder is completed, the Ihinge g'is removed, separating 'the Ways D from the platform, the brace ol is removed, and the ways are swung up upon its. hin-ge e, which connects their foot with the frame I, bringing the cylinder into a vertical position, its lower end' resting upon the step Z, the braces E, in the mean time, detaching themselves, and floating up to the surface. i

In iig. 3 is shown a frame, which is-then placed over the oylinder,resting upon the crib, so that by attachv ing a chain tothe cylinder, and also to the cross-bar-M, which is supported upon jack-screws s, which rest upon the vtop plate Lof the frame, the cylinder can be rnised up by the turning of the screws, when, by drawing upon the` cord or chain p, shown'in iig. 2, the ways and the frame I beneath the cylinderarewithdr'awn, when ,the cylinder is allowed tosettle down `upon the clay or bottom of the lake-or stream.

By clamping Vsaid kframe L to the crib in any suitable manner, and blocking up between the top of the cylinder and the follower or bar N, the turning of the screws above said bar N will force o r drive :The cylinder as and for the purposesldescribed.

Y Vin th'e manner and for the purposes described.

into the clay or soil beneath, if desired.

Having described the construction and opera-tion of my invention, I will specify what I claim, and desire to secure by Letters Patent. 1. I claim the combination and arrangement of the inclined wayD, hinged'at the bottom, as shown, and

the hinged adjustttble platform D", with its means of elevation and depression, substantiellyin the manner :ind for the purposes specified.

2. I claim, in combination with the above, the clamps F f, operating the manner and for the purposes set forth. v

3. In combination with the hinged platform D and ways D, I claim the linked rods 7i, arranged to operate 4. I claim the frame Ii, with its movable bars M N, in combination with thc'wnys D and frarncI, arranged GEORGE R. 'BRAMHALL .Witnesses:
